Will Tiger feel faster?

I recently purchased my first Mac, a Powerbook G4 12" 1.5 ghZ.
I noticed resizing Windows in Panther is really slow, and the OS in general feels more sluggish than Windows (because it does more fancy things, I know).

Will my laptop benefit of Tiger? Isn't it already the case that all stuff in MacOS is rendered through the GPU?

Currently when you resize a window the entire content is redrawn. Based on the available information on Tiger (could not find the link) this is changed. Only the portion which needs redraw will be refreshed. This most likely will improve performance on this particular action.

Holy shit!

If they finally got around to implementing this, then dirty region calculations might actually be put to use. It took me forever to figure out that the API was there but the dirty region info was simply being discarded.

Have they finally fixed the dirty region redraw mechanism in cocoa? That, even without CI, would make a huge difference in speed.

I have the same computer as the original poster. I'm also hoping to have things feel speedier in Tiger. Actually, now that I'm all setup with my new Powerbook and cinema display, the operating system is the next big thing for me. I can't wait until Tiger!

Panther has Quartz Extreme - this is only to speed up COMPOSITING of the graphics, not the drawing. This requires any RADEON or gForceMX or better.

Tiger has a new thing called Core Image, but this is mainly for effects like Photoshop does, i.e. making little programs for the GPU. Core Video is just the same things applied to video.

Now, the really important thing for USERS is Quartz 2-D Extreme. THIS is the feature that sends almost all of the 2-D drawing straight to the GPU using the OpenGL features. This is what speeds up the window resizing. And I have to say I heard a rumor, if you know what I mean, that window resizing on Tiger is finally superfast.

The problem is that Quartz 2-D Extreme requires better GPUs than Quartz Extreme - it will require either a ATI 9600 Pro or better, or an nVidia 5200 go or better. The 9200 in the Mac mini and the 12" PB won't be able to dump those calculations on the GPU and will use Altivec.

Great. Now my new 12 inch Powerbook can't take advantage of Tiger However, the 12 inch has 5200 Go, so why can't it take advantage?

The 12" PB will "take advantage" of Tiger just fine. I can't comment on anything specifically, but I'm using a beta version of Tiger on a 700 Mhz G4 iMac and I think things look good for the most part. Some things are fast, some slow, some buggy, some broken, and I can't claim to have really tested all parts of the OS thoroughly. Also, developers and the quality of their applications make a difference here too, not just the OS or the hardware.

Does anyone know if Safari in Tiger has developed speed? From my personal use, Firefox beats Safari hands down. Has this changed in Tiger? I love the look and feel of Safari and the new features in Tiger seem superb, but I need the speed to catch-up to Firefox.

I agree with BuonRotto. I'm on a 12" iBook and "some things are fast, some slow".

A week ago my 512Mb stick of RAM went bad, so now I'm only running the built-in 256Mb and 8A369 is enjoyable and quite usable.
Spotlight is quite snappyª

interesting to see that the mac browsers are comparable in speed to the x86 platform. People keep complaining that browsing on the mac is so slow, but it seems that safari 2 will make it as fast or faster than anything out there. css, multi image, and tables tests are the 3 that really indicate the browser speed for the most part, and safari 2 will kick butt in those areas. (plus it was just a preview that was tested- good chance the final will be faster)

Also tiger will force developers even more to move away from quickdraw, which will mean more speed in old proggies

Perceived browser speed has a lot to do with partial page display while the page is still being downloaded.

Those stats are encouraging... but only part of the picture. Even if safari displays the final downloaded page quickly, it won't seem quick unless the window is updated numerous times prior to the entire page being fully downloaded.

This is the same crap we went through before with Panther and Jaguar. The thing is if Apple doesn't completly (revamp/rewite/do a vodoo dance) on the FInder the speed issue will still be there, I have the latest Tiger seed and I so far don't see much in improvements in that area. Though everthing else is looking mighty nifty

When I looked up "Ninjas" in Thesaurus.com, it said "Ninja's can't be found" Well played Ninjas, well played.

Ok people i see your point resizing could be slightly faster. But on my machine it isn't a big problem. There's a bit of a lag but if you use column view (like I do) I very rarely change the size of my windows.
